Milliste ülesannete jaoks kasutatakse lazy loading mehhanismi?

Lazy loading mechanism is used for deferred initialization of resources or data until the moment they are actually needed. This helps save memory and loading time of the application, improving performance.

In Android, lazy loading is applied, for example:

• To load images or data from the network only when they are truly needed (e.g., when scrolling through a list).
• To initialize heavy objects or components only upon first access.
• To optimize the loading of UI components so that they are not created all at once.

Example of using lazy loading in Kotlin:

val heavyObject: HeavyClass by lazy {
    println("Initialization of heavyObject")
    HeavyClass()
}

fun useHeavyObject() {
    // heavyObject will be created only on the first call
    heavyObject.doSomething()
}

Thus, lazy loading is used for resource optimization and to improve the responsiveness of the application.
